Rolling regression, which beats the same ARIMA to a pulp

Rolling regression, which beats the same ARIMA

You can't learn everything, and all MO methods are about equal. You can find something suitable practically in any of them, and then you can try the others. But if, say, both Bayesian and NS do not give results, then it is only a waste of time to try the others. All this can be done later, if needed.

Well together they give very good results, it's a question of realization.) Sampling examples via MCMC, training with NS is the best solution so far

to pick up an asset or group of assets for this, then the regression may be useful through MCMC
 
Yuriy Asaulenko:

What's interesting there is variation problems and Theano.

I keep meaning to use variational methods to tune the system, but I haven't found the approaches yet.

Looking for the same thing :)

 
Maxim Dmitrievsky:

well, together they very much do, it's a question of implementation ) Nasample examples through MCMC, i can not think of a better way to train on this nc

Well, it's not the MO, so it's not together.) You don't need libs for Karla).

 
Yuriy Asaulenko:

Well, it's not the MoD, and therefore not together.) For Carla and the libs are not needed.)

Well, while floating on how to put it all together. Through a trivial enumeration of options get results, why exactly get good or not good in one case or another, it is difficult to understand.

I will have to visualize it with similar libs - see.

 
Maxim Dmitrievsky:

Well, I'm still floating on how to put it all together. Through a trivial enumeration of options get results, why exactly get good or not so good in one case or another, it is difficult to understand

Well, we all swim. Only I rarely change options, and more on the couch, either reading (a tablet is a good thing), or think - what to do.) Before doing, well, it would be nice to scroll through it all in my head, and then how to ...

 
Maxim Dmitrievsky:

Comparisons show that there is not much difference... the forest is a classic. In alglib it is perfectly natively present in mt5. I want to update to a new version, but I have troubles with it.

I can, of course, connect a dll, but then how do you make people happy?

If I'm not mistaken - the only difference is the learning speed. Otherwise it should still retrain the same. At least the description has not changed, and limitations on depth, errors, etc. are not added.
And the forest is one of the fastest learning methods, especially compared to the NS.

Yes, but also the classification of the forest is very peculiar. NS or Bayes is closer to fuzzy logic, and to data generalization.

The learning speed is good, the response time when using and the download time of the structure are bad, because the forest files are large. I had up to 300 mb.

There is something wrong with serialization. The forest is trained and saved faster than it is loaded back from the file.

If it says that the forest now generates orders of magnitude smaller files, that's a very big speedup

NS, on the contrary, takes longer to learn, but the response is instantaneous. There is no difference in the quality of classification. You can use anything, but the woods work out of the box, and the NS needs to be adjusted
